Obelisk of Urd

Static anthems normally charge you tempo up front: an enchantment like Glorious Anthem asks for three mana and buys nothing on the board it enters, and the wider the buff, the steeper the toll. Convoke inverts the arithmetic here, letting the swarm that benefits from the pump also foot the bill. A wide tribal aggro deck taps its mob to deploy a six-mana team-wide +2/+2 far ahead of curve, an anthem paid for by creatures already sitting on the table rather than by mana from the manabase. The printed cost line is almost never the real price. There is a genuine bargain buried in that, though: convoke taps the creatures you spend, so the turn you slam it those tappers sit out of the attack. You trade one turn of pressure for a permanent buff, then collect on it every combat after. The +2/+2 also runs larger than the white static anthems it descends from, the concession for being an artifact any color can run and a spell that locks a creature type in on entry. Cast it into an empty board and you get no convoke discount, no chosen type to grow, just a dead six-drop. The bargain only pays out if the swarm is already assembled: build the board first, and the reward is an anthem that arrives early and stays parked.
